Generac Protector Series 45kW - High-Performance 3600 RPM Power
45,000 Watts. 2.4L Liquid-Cooled Engine. Compact & Powerful.
The Generac Protector Series 45kW (Model RG045) is engineered for homeowners and business owners who require high-capacity backup in a compact footprint. Operating at 3600 RPM, this liquid-cooled unit provides 45,000 watts of clean, stable power. Featuring TruePower™ Technology, it ensures less than 5% total harmonic distortion, making it the ideal choice for protecting sensitive modern electronics and heavy-duty appliances during a total power outage.
Purpose-Built Engineering for Reliability
At the heart of the RG045 is a Generac-built 2.4L 4-cylinder engine, designed exclusively for the demands of generator use. It utilizes a first-in-class dual-valve ultra-low pressure fuel delivery system and intelligent proprietary controls that manage over 100 performance functions. This ensures peak efficiency and rapid response across all temperature ranges and elevations, providing seamless power the moment an outage is detected.
Quiet-Test™ Mode
Enjoy quiet maintenance. The Quiet-Test mode runs the generator at a lower RPM for its weekly diagnostic, ensuring the system is ready while consuming less fuel and creating minimal sound disruption.
Integrated Connectivity
Monitor your power from anywhere. Built-in cellular connectivity enables Mobile Link™ for owners to check status on their smartphones, and Fleet for service providers to ensure proactive maintenance.
